Collection company WTF?

Collection company WTF?

Today I got a letter for a collection compay with the usual blah blah. The bill itself is about 5 years old, but I think this is the first I've heard from this agency about it. The back story being, its a doctor bill for my son. My old insurance had a $25 co pay, but the office coded the visits as out patient surgery. After trying to logically deal with them, even getting a rep from both insurance and office on the phone, where the insurance told them just to refile under the correct code, and the doc's office refused to do it(wtf?) I told the doctors billing dept. to go to hell. I technically owe the doctor $75, but due to their crainorectal inversion, they are billing me for $565. I'd like my credit to get better, but I'm afraid to call these people, lest it restart the famous 7 year clock. Any advice?
